I have many years programming experience, but am new to Perl. I have installed Perl on Windows XP Pro with IIS and have a 'hello world' program working. I am trying to set up the W3C Validator. When I click the link that launches 'check.pl' I get the error:-

Can't load 'D:/perl/site/lib/auto/SGML/Parser/OpenSP/OpenSP.dll' for m
+odule SGML::Parser::OpenSP: load_file:The specified module could not 
+be found at D:/perl/site/lib/XSLoader.pm line 66.  at D:/perl/site/li
+b/SGML/Parser/OpenSP.pm line 18

This is mid-way through the initial set of 'use' lines

OpenSP.dll exists in the path as given - so why doesnt it load? I changed XSLoader.pm to have 2 additonal print lines

   print "Loading XSLoader::load for $module ($file)<br>\n";

    my $libref = dl_load_file($file, 0) or do { 
        require Carp;
        Carp::croak("Can't load '$file' for module $module: " . dl_err
+or());
    };
   print "Loaded XSLoader::load for $module ($file)<br>\n";

All the 'use' commands prior to use SGML::Parser::OpenSP show both the 'Loading' and 'Loaded' messages from the print statements. However when this 'use' statement is processed the 'Loading' message is displayed but not the 'Loaded' message - instead the error is generated I am pulling my hair out and shortly will be a 'tonsured monk' Advice greatly appreciated.
